Other seborrheic dermatitis
ICD10CM code
Name of the Condition
- Other Seborrheic Dermatitis (ICD Code: L21.8)
Summary
Seborrheic dermatitis is a common skin condition that primarily affects the scalp, causing scaly patches, red skin, and stubborn dandruff. While it can also impact oily areas of the body, such as the face, upper chest, and back, "Other seborrheic dermatitis" refers to atypical forms not captured by more specific categories.
Causes
The exact cause of seborrheic dermatitis is not well understood. It is believed to be related to an overproduction of skin oil and irritation from a yeast called Malassezia, which is present in the oil secretion on the skin. Genetic predisposition and environmental factors might also play roles.
Risk Factors
- Age: Common in infants (cradle cap) and adults between 30-60 years.
- Gender: More frequent in men.
- Neurological and psychiatric conditions: Parkinson's disease, depression.
- Weakened immune system: HIV/AIDS, organ transplant recipients.
Symptoms
- Red, scaly, and greasy patches of skin.
- Persistent dandruff that doesn't respond to regular treatment.
- Itching or soreness.
- In more severe cases, thick crusts or noticeable plaques.
Diagnosis
- Clinical examination of the affected skin.
- Dermoscopy to assess the scalp or skin lesions.
- Skin biopsy in rare cases, to rule out other conditions with similar presentations.
Treatment Options
- Topical antifungal treatments: Help reduce yeast growth and alleviate symptoms.
- Corticosteroid creams or lotions: Reduce inflammation and itching.
- Medicated shampoos: Contain ingredients like ketoconazole, selenium sulfide, or zinc pyrithione to control dandruff and other symptoms.
Prognosis and Follow-Up
Seborrheic dermatitis is a chronic condition with periods of remission and flare-ups, usually manageable with treatment. Regular follow-up with a dermatologist is essential, especially if symptoms persist or worsen.
Complications
While generally not serious, complications can occur if the condition is untreated, such as secondary bacterial or fungal infections and significant skin discomfort or depression due to visible symptoms.
Lifestyle & Prevention
- Maintain a regular skincare routine to manage oiliness.
- Use gentle, non-irritating skincare products.
- Control stress, which may exacerbate symptoms.
- Dietary adjustments to reduce inflammatory triggers.
When to Seek Professional Help
- Persistent skin rash or dandruff not responsive to over-the-counter treatments.
- Noticeable distress or discomfort due to itching or appearance.
- Signs of secondary infection, such as increased pain, swelling, or pus.
